The amount of energy required to heat 0.5 kilograms of water until the temperature increases 12° C is about
Answer:
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
Explanation
Energy can be calculated by the equation
Q = m x Cp x delta T
where
m = mass = 0.5 kg
Cp = specific heat of water = 4184 J
Delta T = 12 degrees
Multiplying all
Q = 0.5 x 4184 x 12 = 25104 Joules
Converting it to Calories
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
what is hail stones?why is oxygen
Answer:
hailstones --> Hail is a type of precipitation, or water in the atmosphere. Hail is formed when drops of water freeze together in the cold upper regions of thunderstorm clouds. These chunks of ice are called hailstones. Most hailstones measure between 5 millimeters and 15 centimeters in diameter, and can be round or jagged.

Why does the mitochondrial gene tree suggest a later split? Why the disparity between the nuclear gene tree?
this is the link: https://learn.genetics.utah.edu/content/evolution/bears/
Answer:
Why does the mitochondrial gene tree suggest a later split?The mitochondrial gene tree suggests a later split because it occurred hybridization later in time, with the transference of the brown bear mitochondrial genetic information to the polar bear population. So the mitochondrial gene tree exhibits a later divergence.
Why the disparity between the nuclear gene tree?Because the first divergence event of the common ancestor occurred 60,000 years ago, evidenced by nuclear DNI and mitochondrial DNI. However, 100,000 years ago, concerning the mitochondrial genetic material, the hybridization event defined a new more recent common ancestor between the two species.
Explanation:
The use of mitochondrial DNA might present a few problems that need to be considered in evolution studies. It involves only one locus, so it has some limitations when reconstructing history, especially if the locus went through any process, such as natural selection, bottleneck events, or its transference to another population due to hybridization. There is also a high possibility of an incomplete reconstruction of the population history if males and females have different dispersal patterns.
The most proper way of reconstructing history is by complementing mitochondrial information with nuclear genetic information and evaluating their concordancies.
In the exposed example, 600,000 years ago, the original species split into the polar bear and the brown bear. But 100,000 years ago, hybridization occurred between a brown bear female and a polar bear male. The offspring joined the polar bear population, carrying the female genetic information, nuclear and mitochondrial. With time, these individuals interbred with the polar bears, diluting the nuclear brown bear genetic information. However, females carrying the brown bear mitochondrial DNI seemed to be more successful reproductively than the polar bear females. The mitochondrial information, hence, has been in the population for many generations, until today. And this information came from a more recent common ancestor, compared with nuclear genetic information.

Describe the motion of the molecules in the cold water in terms of their kinetic energy.
Answer:
As ice melts into water kinetic energy is being added to the particles.This causes them to be "excited" and they break the bonds that hold them together as a solid resulting in a change of state:solid -> liquid.

Research the differences that exist between mitosis and binary fission. Identify at least one difference, and explain why it is significant.
The difference between mitosis and binary fission is that while mitosis occurs in eukaryotes and binary fission occurs in prokaryotes.
Mitosis and binary fission are forms of cell division that duplicate cells. Binary fission occurs in prokaryotes which are the cells that do not contain a nucleus.
On the other hand, mitosis occurs among the eukaryotes which are the cells that have a nucleus. Also, binary fission doesn't include spindle formation in its process which makes it faster than mitosis.

When an object is already in motion, why is energy required to stop it
When an object is already in motion then we require force to stop it because due to inertia , a body tends to remain in the state of motion unless an external force acts on it .This is in accordance with Newton's first law of motion or law of inertia of motion.
What is inertia ?Inertia is the tendency of a body to remain the way it is. It opposes any changes to its state of rest or motion.
The more is the mass of the body , the greater will be the inertia.
What is external force?External force is the force applied by external agents on the body.

Which of the following is NOT true of a reaction that breaks a bond?
A. It creates low-energy products
B. It is what happens in cellular respiration
C. It is an endergonic reaction
Answer:
C
Explanation:
Endergonic reactions use energy to build bonds
Exergonic reactions release energy through breaking bonds
C. It is an endergonic reaction.
Endergonic v/s Exergonic:
In the exergonic reaction, the reactants are at a higher free energy level than the products (reaction goes energetically downhill) while In the endergonic reaction reaction, the reactants are at a lower free energy level than the products (reaction goes energetically uphill). Endergonic reactions use energy to build bonds while Exergonic reactions release energy through breaking bonds.When a bond breaks, it creates low-energy products.In cellular respiration, breaking of bond happens.Therefore, the statement which is NOT true for a reaction that breaks a bond is option C.

Explanation:
Red-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatching. Explain your answer in 1–2 sentences.
Natural selection inhibited the eggs from hatching before expected because this trait is negative in terms of survival and reproduction.
How does natural selection work?Natural selection is a natural process that causes evolution over time. This mechanism implies only individuals with traits that represent an advantage for survival and reproduction will prevail over time, which causes the traits of these individuals to become dominant.
For example, if in a population of deer male deer with big antlers are more likely to survive and reproduce, it is expected after some generations this trait is dominant.
How does natural selection work in the red-eyed tree frog case?In this situation, we know that if an egg hatches before time the embryo is not likely to survive. This means this trait is a disadvantage in terms of survival and reproduction, and due to this and as a result of natural selection the trait is not dominant.
